Title:
MULTI-WAVELENGTH LIGHT SOURCE MODULE
Document Type and Number:
WIPO Patent Application WO/2023/013418
Kind Code:
A1
Abstract:
A multi-wavelength light source module (10) comprises a plurality of first sets and a plurality of second sets disposed on a major surface (21) of a base (20). The first sets include a first semiconductor laser chip (51) having a first optical axis parallel to the major surface (21) and emitting first light of a first wavelength band, and a first mirror (61) reflecting the first light in a direction perpendicular to the major surface (21). The second sets include a second semiconductor laser chip (52) having a second optical axis parallel to the major surface (21) and emitting second light of a second wavelength band different from the first wavelength band, and a second mirror (62) reflecting the second light in a direction perpendicular to the major surface (21). The first optical axis is perpendicular to the second optical axis. The polarization direction of the first light propagating from the first semiconductor laser chip (51) to the first mirror (61) and the polarization direction of the second light propagating from the second semiconductor laser chip (52) to the second mirror (62) are orthogonal to each other.
